Equipment I would find unyielding (5)
I believe the answer is:
rigid
'unyielding' is the definition.
(I've seen this before)
'equipment i would' is the wordplay.
'equipment' becomes 'rig' (rig is a kind of equipment).
'i would' becomes 'I'd'.
'rig'+'id'='RIGID'
'find' is the link.
(Other definitions for rigid that I've seen before include "Stiff, unbending" , "Frozen" , "Not flexible" , "completely" , "Stiff and inflexible" .)
